About this video: Many people worry sunscreen blocks vitamin D production — but is that really true? Here’s what the science actually says.

The key is balance — protecting your skin while still allowing safe, incidental exposure.
Watch this short explainer to learn why sunscreen, used correctly, protects your health without stopping your body from making vitamin D.
